HITCHING- APPLIANCE.

Specification of Letters Patent.

Patented July 6, 1915.

Application led October 3, 1914. Serial No. 864,799.

T0 all whom it may concern f Be it known that l, HARRY B. SAwYnn, a citizen of the United States, residing at Ogden, in the county of llleber and State of Utah, have invented certain new and useful Improvements in l'litching- Appliances; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hitching appliances, and in particular to bitching appliances attached to the hub of a vehicle wheel.

One of the objects of this invention is to give a device that will allow of a hitching arrangement every few degrees of the circumference.

Another object of this invention is to give a device that will give an absolute bitching arrangement irrespective of its point of connection.

Another object of this invention is to give a device which is integrally incorporated in the hub of a vehicle wheel inside of the line of the spokes.

Other objects and advantages of' this invention will be hereinafter more clearly set forth in the specification and pointed out in the claims.

Similar characters of reference refer to similar parts throughout the various views of the drawings, in which,

Figure 1 is a transverse sectional view of my device as applied to the hub of the vehicle wheel, and Fig. 2 is a sectional view on the line 2-2 of Fig. 1.

rlhis application is an improvement over former application iled July 3, 1914, Serial No. 848,336.

ln the drawings, 1 is the hub of my vehicle wheel inclosed in a shell or casing 2 which in general conforms to the contour of the hub 1, which is composed of two sections, an inner section 3 and an outer section 4, said outer section 4 having an out-turned flange 5 with suitable perforations therethrough to lock said section 4 to an outturned flange 6 of the section 3 by means of bolts 7 or other suitable form of fastening device which passes through the spokes 8 of the vehicle wheel. An annular projecting and integral flange 9 and spaced parallelly with the llange 6, is had upon the section 3,

and likewise a plurality of socket depres sions 10 are formed in the section 3, each of said socket depressions having one angularly disposed side ll and one slopingly disposed side 12 for a purpose hereinafter more clearly set forth. A face plate 13 having an offset portion 14 around the peripheral section thereto with a plurality of apertures 15 therein is mounted upon the section 3 of the shell until it abuts against the previously mentioned flange 9, said face plate 13 being in the form of a ring for this purpose. A wooden or other suitable form of filling block 16, said block being in the form of a ring is mounted uponthe casing 3 to abut `against the face plate 13 previously noted, after which, a second ring-like face plate 17 is mounted upon the casing 3 and said face plates are fastened by means of bolts or rivets 18 which passes through each of said face plates and said filling block 16, as plainly shown in Fig. 1. An annular collar 19 is then mounted upon the casing 3 which locks my device upon the wheel, said locking being attained by means of set screws 2O which are threaded through the collar so as to bite into suitable depressions 2l in the outer face of the section 3.

My filling block 16 is composed substantially of an annular ringlike structure having a plurality of recesses 22 therein, said recesses ending in a channel-like recess 23. A bearing plate 24 is mounted in the recess and is adapted to bear against the casing 3 of the hub and said plate 24 is pressed against the casing 3 by means of a coil spring 25 which is seated in the recess 22. A second series of recesses 26 is had in the wooden ring, said recesses opening to the sections 3. These last mentioned recesses are placed mid-way between each of the first mentioned recesses 22. A pivoted dog 27 is mounted in these recesses, said dog being pivoted by means of a transverse pivot pin 28, said dog being positioned in the walls of the face plates 13 and 17 by means of washers 29 and 30 placed on each side of the dog and between said face plates, said washers likewise being mounted upon the pivot pin 28. At the biting end of the dog 27 is an angular sloping edge 31 and a second sloping angular edge 32 disposed at right angles to the angular edge 31 to there by give a biting point 33 plainly shown in Fig. 2 of the drawings. This biting point is adapted to seat against the hub 1 of the Wheel and the angular side 11 of the recesses 10 previously noted, thereby giving absovlute locking arrangement With a comparatively maximum degree of strength. The

' sloping edge 12, previously noted tends to lead the dog 27 out of the recess 10 upon the rotation of the hitching device.

In use, the Wheel is mounted upon the usual vehicle axle 34 having the thimble 35 thereupon, said Wheel being locked with hub, said sectional shell casing having an annular flange thereto With a number of perforations therein, a second annular flange parallelly spaced from said first mentioned flange, aplurality of recesses With angular and sloping faces thereto adjacent said second mentioned ange, a second sectional shell casing having an out-turned annular flange mounted upon said hub, a plurality 4of fastening means mounted through the flanges on each of said shell casings and through the spokes of the Wheel and fastening' said shellcasings upon the hub, a hitching device mounted upon said first mentioned shell casing and abutting said second mentioned flange, and an annular collar mounted upon said sectional shell cas- Copies of this patent may be obtained for ing locking said hitching device into operative position by means of set screws.

2. A hitching device comprising; a vehicle Wheel, a shell to the hub of said Wheel having an out-turned annular flange, a ringlike face plate abutting said annular flange,

a lling block abutting said ring-like face plate, a second ringdike face plate abutting said filling block, fastening means mounted through each of said face plates and said filling block and locking said assembled device into operative formation, an annular ring abutting said assembled device and means in said annular ring to seat the same upon the hub of a vehicle Wheel.

3. A hitching device comprising, a vehicle Wheel, having a shell upon the hub thereof, a hitching device rotatively mounted upon said shell and rigidly retained thereon, filling means Within said hitching device, locking dogs Within said hitching device said loeking dogs having a first mentioned angular edge and a second mentioned angular edge at right angles to said first mentioned angular edge, and a plurality of recesses in said shell each having one angular and one sloping Wall, said angular Wall adapted to seat said angular edges of said dog into locking engagement and said sloping Wall adapted to lead said dog out of said recesses upon the rotation of the Wheel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
